An early warning method for greenhouse irrigation pipeline system

Abstract

The invention discloses an early warning method for a greenhouse irrigation pipeline system, which includes an irrigation pipeline system, an initial liquid level calibration stage, a liquid level change monitoring stage and an alarm component. When in use, an electric push rod is used to support the installation frame, and the installation frame is placed Above the greenhouse nursery, the water storage device is installed outside the greenhouse. The water flow enters the first irrigation pipe from the three-way pipe, and the water flows out from the irrigation port to irrigate the plants below the irrigation port. Into the irrigation pipeline system, realize the automatic switching of the water inlet mode, in rainy weather, use rainwater instead of tap water to irrigate plants, save irrigation costs, and be more environmentally friendly; determine that the amount of tap water intake cannot meet the irrigation needs or determine that the irrigation pipeline is in an abnormal state , The alarm component is continuously turned on, and the staff can judge the cause of the system failure through the status of the alarm component, which is convenient for the staff to investigate in time, realize timely rectification and maintenance, and has better practicability.

Description

technical field [0001] The invention relates to the technical field of greenhouse plant irrigation, in particular to an early warning method for a greenhouse irrigation pipeline system. Background technique [0002] Precision agriculture is a new type of field management. The characteristics of field soil and crops in the farmland are not uniform, and generally change with time and space. Traditional farmland management believes that these factors are uniform, so the uniform Compared with traditional agriculture, precision agriculture has the following three characteristics: 1. Reasonable application of chemical fertilizers, reducing production costs; 2. Reduce and save water resources; 3. Saving costs and increasing efficiency. Saving labor and time, high quality and high yield, automatic irrigation system is an important part of precision agriculture. The existing greenhouse irrigation pipeline system mostly uses tap water as the water supply source. When the irrigation vo...

[0003] The purpose of the present invention is to provide an early warning method for greenhouse irrigation piping system, by using rainwater instead of tap water to irrigate plants in rainy weather, saving irrigation costs and being more environmentally friendly, staff can judge system failures through the status of alarm components The reason is that it is convenient for the staff to check in time, realize timely rectification and maintenance, and has better practicability. To solve the problem that the greenhouse irrigation pipeline system proposed in the above background technology mostly uses tap water as the water supply source. When the irrigation volume is large and the irrigation time is long, The cost input is greatly increased. If natural precipitation is used as the water supply source, the water supply method needs to be manually replaced with tap water supply during the non-precipitation period, which is inconvenient to operate. Moreover, the existing greenhouse irrigation pipeline system is composed of multiple pipelines, and the pipelines are connected to each other. , the number of pipes is large, once any pipe is blocked, it will affect the irrigation effect of the entire irrigation system, the staff cannot repair the fault in time, and the problem of poor practicability
